In order to gauge how accurately the averages represented the fibers, the standard deviations of the widths were also plotted. On histogram B the distribution of the standard deviation of width of each fiber is shown. Over ninety percent of the fibers' widths deviate by less than .03mm on average (1.5% of the maximum desired width). Considering histograms A and B, there are very few fibers that are too large or uneven to use.

==Comparison Among Spools==
Every fiber was cut from one of four spools delivered by the manufacturer. The spools are named "A1", "A2", "S1", and "S2"
